Oh wow, that's awesome. I will try that and if that works, I can get for sure a good car for towing 1574kg
I am not too sure what this meant at first, but my license has a BE code on the back with a little picture of a tow car and validity dates that are in date, so I guess that means yes I have it.
This this thread was resurrected and I am the OP, just to provide an update here, in the end I went for a Volvo XC60 T8 Recharge - I did this partly because they had really good 0% finance and finance contribution offers which made it a good value deal compared to the other cars I was looking at, and also because it will pretty much tow any caravan that we could possibly consider.
The Porsche Cayenne was really good to drive but was just too expensive to justify in the end, especially as they don't seem to offer any significant discounts and you have to pay a huge amount extra to spec it up to the same level, and the finance interest rate is high. Also it sits massively high off the ground and my wife is quite short and joked that she might need a ladder to get into it!
After looking at a lot more caravans we might end up going for a Bailey Pegasus Bologna which is larger than what we originally intended and is twin axle - this is mainly because we like the side fixed bed layout with rear bathroom, and the lighter caravans makes it difficult to access the bathroom when the bed is extended - I particularly found this with the Swift Sprite which basically completely blocks you from walking to the bathroom.
The car seems fantastic so far - next step is to book a towing class for both of us an dthen buy the caravan early next year!
